On January 8, 10 students come down with the flu. Assume that each day, the number of students who come down with the flu doubles. So, for example, 20 students come down with the flu on Jan. 9. Let f(t) represent the number fo students who come down with the flu at t days since Jan.8.

a) Find an equation for f

Hopefully this is right f(t)=10(2)^t

b)Find f(7). What does your result mean in terms of the situation?

f(t)=10(2)^7

1280 In 7 days since January 8 which will be January 15, 1280 students will have the flu.
